I love the luxe idea of cashmere in not-longsleeve items, but end up finding it seasonally confused, and also I have no idea how to prevent such items from being moth-bait. Meaning, I try to wear my winter cashmere sweaters with at least a short sleeved underlayer (tanks may help too, but don't line the underarm area well, even if if very light cotton such as the really light Hanro undershirt, thinking this means it won't be as much moth-candy, since not planning to wash after every wear. Whereas sleeveless and SS tops are often underlayers of some sort themselves.
I do bank on the idea that moths may not be as drawn to items hanging spread apart in closet, with light, as during off -season storage, but I'm not sure.
I've always wondered about the discrepancy between, "only store clean, washed or dry-cleaned woolen sweaters" vs how one goes through a winter season, typically (( assume) wearing such sweaters at least several times between washings, and putting them in drawers (recommended for sweaters), or even hanging them, as I do.
I had been thinking of getting, in future, something like a merino "active" T shirt for travel, since I don't think the moths travel and since the active-wear brands tend to be marketed as more durable for washing.
YMMV if you have never had any moth issues.
